Patented Feb. 24, 1931 UNITED STATES PATENT OFFICE MEANS FOR NEUTRALIZIHG POISONOUS ENGINE GASES Application filed October 20, 1926. Serial No. 143,007.

The invention relates to means for neutralizing poisonous engine gases, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially of the novel features of construction pointed out boardly and specifically in the claims for nov: elty following a description containing an explanation in detail of an acceptable form of the invention.

The objects of the invention are to eliminate the disastrous results to persons occupying enclosed areas within reach and in communication with the exhaust gases from a gasoline or like motor, where the generation of carbon monoxide gas proves a common menace to motorists; to aiford an easy passage for the used gases, that will at the same time facilitate the admixture of the neutralizing agent; to screen the flow of the outgoing gases to an extent suflicient to produce a harmless discharge; to permit the operation of internal combustion engines in 2; closed garages and such places; to furnish a safety device that will be. equally eflicient for closed cars while travelling and save the occupants from the sickening effect of the apparently innocent gas from which no par- 30 ticular odor arises and in place substitute a healthy atmosphere within the vehicle notwithstanding the escape of engine gases therewithin; and generally to remove from amongst the motorists troubles, one that has 35 proved of serious proportions including the loss of many lives.

In the drawings, Figure 1 is a longitudinal sectional view of the neutralizer.

Figure 2 is a sectional plan view showing 49 the relation of the neutralizer to the engine.

Figure 3 is a cross sectional view on the line 3-3 in Figure 1.

Figure 4 is a cross sectional view on the line 4-4 in Figure 1.

Figure 5 is a cross sectional view on the line 55 in Figure 1.

Referring to the drawings, the casing 10 may be made of sheet metal or other suitable material and of box shape in cross section, 50 having the semi-cylindrical bottom 11 and the extended and inwardly curved outer wall 12 and the straight inner wall 13, from which the flanged inlet passages 14, 15, 16 and 17 may extend to the cylinders 18 direct as shown or to an exhaust manifold 19 in any approved manner according to the type of engine,

these inlets are bolted through their flanges 20 to the engine and the passages communicate with the exhaust gases to bring them within the casing 10. 60

The casing 10 at one end is closed by the permanent end wall 21 having the central flaring air inlet 22, which may be removable if desirable. V

The other end of the casing 10 is flanged outwardly at 23 and through this flange bolted to the head 24. The head 24 forms the circular flanged outlet 25 to which is attached the cylindrical cleaner casing 26 flanged at both ends 27 and 28, the flanged end 27 being secured to the head 24.

The tapered nose 29 is also flanged at both ends 30 and 31 and is secured to the cleaner casing flange 28 through the flange 30 and to the exhaust pipe 32 through the flange 31.

The liner rings 33, 34, 35 and 36 are of open oonvolute formation incross section and are secured to the casing 10, except opposite the inlets 14, 15, 16 and 17 where each liner forms an open convolute and at the same time the deflectors 37 38, 39 and 40 extending'in each instance over the line of the air inlet opening through the permanent end.

The liner rings 33 and 34 are divided from one another to form the chambers 41 and'85 42 by the screens 43 and 44 of fine mesh and spaced by the ring 45 and the liners 35 and 36 are divided by the screens 47 and 48 to form the chambers 49 and 50 as well as the screens 51 and '52 and the screens 53 and 54, each. of the last three screen sets bein spaced by a ring indicated at 55, 56 and 5% respectively.

The last two screens 53 and 54 are well within the head 24, so far as the casing 10 is as concerned, which with the flanged head forms an outlet chamber 60 into the cleaner casing 26, where the gases are met by a succession of screens 58 separated by the spacer rings 59.

The ring 61 inserted between theflanges 28 I0 and 31 is inserted in securing the parts tov v gether.

The liner ring 61 spaces the head 24.- from the dividing members to form the outlet chamber.

The material for the liner rings is preferably oxidized copper and the formation as explained is convolute cross section. The extreme upper wall of each of these liners reaches towards an inlet and is securedto the upper casing wall while the outer side vof the intermediate wall of each liner is turned inwardly, so that the backs deflect the gases from the several inlets beyond the inrush of air, each liner being so directed as to cause the gases to swirl around in the aforesaid chambers, these gases being picked up by the air, pumped in to the machine at one end by the pump 62 and eventually delivered from the'other through the exhaust pipe, V

and carried along, said gases being converted from carbon mon-oxide to carbon di-oxide by the oxidized copper sieves and rings, which are reoxidized by the air flowing through. which also intermingles with the gases, flowing into the exhaust pipe to render them harmless.

The gases pass into and through the several chambers and so raise the temperature to a high degree and catalysis occurs in relation to said gases by their cont ct with the oxidized copper and then find xit through the sieves of the cleaner continuing through the tapered pipe forming the nose which is openly connected to the exhaust pipe.

What I claim is 1. In means for neutralizing poisonous gases, a tubular member having convolute catalyzing linings forming inlets connected to the exhaust manifold of the engine, catalyzing screens dividing said linings and means for forcing air through said tubular member from one end to the outlet thereof.

2. In means for neutralizing poisonous gases a plurality of converting chambers formed of an outer casing of partly cylindrical formation having tran verse inlet passages respectively to the chambers and a cylindrical extension from the last chamber,=

liners of catalytic material formed in open 'convolute shape and closed in by screens of catalytic material, sieves forming cleaners in said cyllndr cal extension, a tapered nose ex I tension from said cleaner, an e aust pipe receiving the gases from said'nose, a d an air director and pump delivering air into and in a. longitudinal direction through said converting chamber.-
